What clear pictures! The ghost glassfish looks amazing. . . as well as the neon tetras! I'm thinking about getting a couple ghost glassfish for my tank soon!
Unlike glass fish, glass Cats are not commercially dyed. They would never survive it, mostly because they are extremely sensitive fish, and prone to infection. Which is good, because glass cats are so much more popular than glass fish that if they were more hardy, there would be a dyed kind.
